The Schedule referred 'to in thes'e Letter! Patent and making plrt of the lama.

justing Gar-Axle Box; and I 'do hereby declare the following to be a full, clear, and exact description thereof, which will enable others skilled in the art to which my invention appertains, to make and use thel saine, reference being had to the accompanying drawings, forming part of' this specification, in which- Figure 1 is a` longitudinal section ot' vmy improved car-axle box, taken in the line n x, iig. 2, and applied `to a car-axle.

Figure 2 is a transverse vertical section of thesarne, in the line y' y, fig. 1.

Figure 3 is a similar section of' a' modification of the method of attaching the box to the hanger` of a railroad-Year.

Figures 4 and 5 are detached plan views of figs. 2 and 3, respectively.v f

Iiigin'e 6 is a perspective view of the notched or corrugated wedge by'which the position of the journalbox is regulated with relation to the journal of the axle.

Similar letters of reference indicatel corresponding parts in the several figures.

This invention'rclates to car-axle boxes, and has for its object to simplify their construction, andv to render them self-piling, and adjustable with relation to the cari` and axle. v

It consists, first,` in the combination of devices for compensating for the wear of the journal-box, so that the latter may be nearly consumed before the necessity arises for its renewal.

It consists, secondly, in adiusting the lateral movement of the 'axle to regulate the motion of the cars from side to side, as the irregularities of' the track may demand, to roduce an easy motion of the cars.

It consists, thirdly, in the combination, with the- Yshell of the. axle-box and the ear-axle, of a flange and gasket, formed concentricllyto each other upon the shell, and an adjustable collar placed upon the axle, whereby the oil is retained within the shell, and the dirt prevented from entering the same; the adjuster bility of the collar serving, also, to regulate the lateral movement of the cars.

It consists, fourthly, in the combination, with the shell, of a convex projection formed upon its` upper surface,and guides, having convex proximate surfaces, formed upon two opposite sides of said'shell, whereby the box is rendered capable of oscillatory motion -within its hanger, for' the purpose of accommodating itself to the varying position of'- the axle in passing over an uneven track, and thereby cause the box and journal of the axle to wear evenly.

It consists, lastly, invthe'combination, with the shell, of a passage-or channel, in which the oily residuum `cars 1n the usual manner.

from the shell is received, and fromwhich itis discharged below ther journal of .theiaxla'as-will'be' hereinafter more fully described. I

In the accompanying drawings'-v Y A is the shell oi'a car axle box, of the form shown, and composed of casteil-on or other suitable material.

Upon the' inner side ofthe shell is a circular flange, B, and gasket 0,'the latter' being arranged concentr cally within the former, to leave an 'annular space between them, for the reception of the flange @,oftll'e collar I). This collar Ais adjustably attached'toth'e c areaxle E, by means of' the 'set-screw u., or other suit? able device: y The' end b, ofthe car-axle joui-nal, enters the shell lA, and rests in oontactwith the ii'opt side of thesame,l

which is strengthened atv 1,'as shown in tig. l.

E is the journal-box, composed of suitable boxlmetal, arranged upon the journahto sustain the weightofthe G is a' metal block, attached to or castlupon the under surface ot' the top plate of the shelhabove the journal-box F. This block is inclined upon its under surface, as shown, and provided with transverse notches orcorrugations, e.

I is a wedge-shaped vmetallicI block, arrangedbetween the box F and block G, and provided, upon its upper-surface, with transverse notches f, arranged in a reverse position to those 'upon thel block G.

The block H is made adjustable longitudilllly, by means ofthe screw I and set-nuts g, said screw' passing through a lug or projection, h, iormedA upon the under surface of the top plat-e of the shell, as clearly shown in fig. 1. v

When the vbox F is first applied to the journal, the

wedge H will rest upon its upper surface, and,'a's the n box becomes worn, the wedge is forced inward, by means' of the screw I, to compensate for such wear, the notches upon the blocks G and H fitting into one another, as previously mentioned, in sucha manner as to prevent the'wedge from working outward.

When the box F has become worn to such an extent as to render the wedge alone no longer available for its adjustment, a strip of metal, t',v is inserted between the wedge and box, to which may be added,

from time to time, as necessity-demands, other and4 thinner metallic strips, j.

These latter strips are held'npou the strip i by means i of the transverse groove k, in. the latter, and corresponding projections upon the under' Surface of the Strip J'- By this arrangement, boxes can be used untilnearly consumed, thereby resulting inl a great saving of expensive material.

J is a sliding door, through which the lubricatingmaterial is introduced into the box.v l

Kis -a passage or channel extending wenn@ the sides and bottom of the shell, and communicating with the interior of the same, by- 'means of the slot-.1, in the bottom.

The shell can be filled with oil to any desired height, or so that the journal shall be partially immersed. It is prevented from escaping at the inner end of the shell. by means ofthe joint formed by the flange B and gasket, G, embracing the flange of the collar 1).

It is desirable, in order to renderthis joint perfectly `tight,'to provide the gasket with interior and exterior packing-strips, m, of India rubber, or other suitable material, resting, respectively, in ,contact with the axle E and flange ofthe collar D. Y A

The exterior Iiange serves eiectually to exclude all dust and dirt from the journal.

Thisconstruction of a journal-box insures the constant and perfect lubrication of the journal, and avoids the use of waste and equivalent materials, which are expensive and unreliable. v

:The oily residuum 'within the shell settles to the bottom, and is withdrawn from the channel by removin the plug n, or by other proper means'.

It will be observed that theend b, of the journal, and the shoulder o, at its inner end, Vbear evenly upon the strengthened portion d, at the outer side of th'e shell, and the'shoulder p, at its inner side, but by changing tlie'position of the collar D upon the axle, the distance between' b and d, and aand p-will 'be iiicreased or diminished to adjust the lateral throw Iof the axle, and thereby regulate the movement of the cars fromside to side, to produce an easy motion.'

L are trunnions, aiflxed to oppositesides of the shell, or cast thereon, by which said shell is suspended within the hanger attached to the plat-form of the car.'

In order to shorten the ordinary hangers, and to partially relieve the trunnions ofv the weight of the cars, the upper surface of the shell is provided with a convex' projection, M, upon which the platform of the car By means of the trunnious and the convex projection, the shell is adapted tooscllate in the hanger, to pleservethe parallelism of the box F and journal of the axle, and, as a consequence, prevents-the unequal wear of each.

Instead of employing the trunnions for suspending in dotted lines, fig. 1, may be -formed upon opposite sides of the shell, with their proximate edges made convex.

When applied to the hanger whose sides are parallel, it will be apparent that the shelll is susceptible of oscillatory motion. My improved box is applicable to ordinary shaftin'g', as-well as to car-axles. Itis simplejin construction,

. Having thusdescribed my invention,

What I claim as new, and desire to secure ters Patent, is
